Specification of Letters Patent.

Patented Apr. 15,1919.

Application filed september 25, 1918. Seral No. 255,711.

To all whom it may concern:

Be it known that I, GEORGE-D. BALDWIN, a citizen ofthe United States, and aresident of Hoboken, Hudson county, NewJersey have invented a new and useful Improvement in Power Pipe-Lines, of which the following 18 a full, clear, and exact deseription.

My invention relates to improvements in power pipelines, and especially in pipe lines adapted for use in connection with railroad building. In my application for Letters Patent of the United States No.'215,716,

flied February 7 1918, I have disclosed a track building and to reduce labor cost.

In laying track to advantage, many power driven pieces of apparatus are now used, for instance such as spiking machines, tamping machines, riveters, and the like, and the object of my invention is to provide a simple and ready means for extending a pipeline out over the temporary track or the track that is being built or repaired, which pipe line carries pressure fluid and from which power can be taken to drive any desired mechanism. Generally the pressure fluid used would be compressed air, but obviously any suitable pressure fluid can be used. In carrying my invention into effect I provide pipe sections on individual trucks which are adapted to be extended out in advance of the construction train, provide suitable con nection between the pipes on adjacent trucks, also provide means for taking the pressure fluid to the pipes from the construction train or other source of supply, and arrange valves at the pipe ends so that the flow can be checked at any desired point. I also provide means for taking off the power or pressure fluid at desired points. My invention it will be seen does not lie in any details of construction, but rather in the organization and arrangement of apparatus which can be conveniently extended in front of a construction train or other base, to supply pressure fluid to diflerent pieces of mechanism.

Reference is to be had to the accompany ingdrawings forming a part of this specification, in which similar reference characters indicate corresponding parts in allthe views.

Figure 1 is a plan View of the apparatus embodying my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a cross section through the track and one of the pipe carrying trucks, and

Fig. 4 is a side elevation on a much re duced scale showing how the several trucks and pipes can be extended.

I have shown a source of pressure fluid supply 10 which can be an air compressor, compressed air tank, or other source of supply, and thisas illustrated is carried on a railway car 11, although it can be at any convenient point which forms the base of sup ply and from which the pressure carrying pipes are extended. Assuming the source of supply to be on the car 11, I have shown a bridge 12 connecting with trucks 13 which are adapted to be run out in advance of the completed road or on the road to be re paired, in advance of the source of supply 10, and these trucks 13 run on the tempo rary track 1 1 or other track, each carries a pipe15, and the pipes of the several trucks connect by a hose coupling 16 or other suitable coupling so as to make a continuous power conduit. They likewise connect with the source of supply 10, and each pipe section 15 on a truck 13, has at least one connection 17 from which pressure fluid for power purposes can be drawn off through a flexible pipe 18 or the like. It will be seen that this pipe can be extended to any necessary distance so as to connect with a desired piece of power driven apparatus.

Each pipe section 15 is provided with a valve 19 near the ends of the track 13 which carries it, and so the supply of pressure fluid can be controlled, and if the extensible pipe line is run out on a series of trucks, the valve 19 farthest from the base would obviously be closed, and the power can then be taken from any necessary points along the extended pipe line.

As before remarked, I have shown in the drawings a very simple, convenient and' practical means of carrying my invention into efiect, but obviously the character of the track or of the trucks which carry the several pipes, or the pipe connections, can be changed at will without afl'ecting the in vention, which lies in the extensible pipe" line connected with the source of pressure fluid supply and adapted to be extended out of pipes adapted to carry pressure fluid and mounted on supports, each pipe having a connection from which power may be taken and delivered to points extraneous of the supports, a flexible connection between the several pipes, and a source of pressure fluid supply for the pipes.

3. An apparatus of the kind described comprising a train of portable trucks, a pipe line adapted to carry pressure fluid mounted 011 the trucks and having flexible connections between the trucks, means for withdrawing pressure fluid from different parts of the' pipe line and delivering it to points extraneous of the train of trucks, and a source of 7 pressure fluid supply for pipe line.

4. An apparatus of the kind described comprising a series of railway trucks, pipes adapted to carry pressure fluid located on the trucks, flexible connections between the pipes on the several trucks, means for drawing ofi' pressure fluid from difl'erent parts of the pipe line and delivering it to mechanism along but not on the train of trucks, and a source of pressure fluid supply for the pipe line.

5. An apparatus of the kind described comprising a railway truck carrying a source of pressure fluid supply, means for extending a train of-trucks in advance of the truck carrying pressure fluid, a pipe line carried on the extended trucks, means for withdrawing pressure fluid from various parts of the line and delivering it to points along but not on the line of trucks, and a connection between the source of pressure fluid supply and thepipe line.

6. A an apparatus of the kind described comprising a railway truck carrying a source of pressure fluid supply, an extensi ble pipe line connected with said source of pressure fluid supply, portable means for extending the pipe along the track in advance of the aforesaid railway truck, and means for withdrawing pressure fluid from diflerent parts of the pipe and to supply power: driven apparatus at points along the said line.
